This is the first appearance of recurring stars Ethan Supplee as as Frankie 'the Enforcer' Stechino Jr., Blake Soper as Joey 'the Rat' Epstein, and Danny McNulty as Harley Keiner.
Cory: Mr. Feeny?!
Mr. Feeny: The legend continues.
Cory: Eric, what are you doing here?
Eric: I have no idea, but I know that I'm not going to stand around and watch you beat up some kid that I-I don't even know at all. Ok, he's my brother.
